## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mail-routing-readiness-checker-mx-spf-dmarc-b289c8ea -d '<json body>'
```

Example prompt: Can you check whether acmecorp.com has its MX, SPF, and DMARC DNS records properly set up for mail routing?

## When to prefer this

Use this endpoint when you need a combined, single-call DNS audit covering MX, SPF, and DMARC together rather than querying each record type separately. Ideal for IT admins, email deliverability checks, onboarding workflows, or troubleshooting mail routing issues. Not suitable if you need to verify that a specific inbox exists or to actually send a test email.

## Known failure modes

- Domain does not exist in DNS — may return empty or error results
- DNS lookup timeout for slow or unresponsive nameservers
- Malformed domain input returns validation error
- Domain has no MX, SPF, or DMARC records — returns empty fields rather than an error

## How this service works

Mail routing readiness for IT administration: Check MX, SPF, and DMARC DNS records together. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns DNS record data for the specified domain including MX (mail exchanger) records, SPF (Sender Policy Framework) TXT record, and DMARC policy record — giving a combined view of the domain's mail routing readiness. Does not send email or verify inbox existence.
